Hydraulic Systems
General Info
Ensure that the snap couplers are clean before connection! Failure to do so will cause premature wear to the hydraulic
system.
After having operated the boom, and the system has been filled with oil, check the tractor's hydraulic oil level, and top up if
necessary.
€
DANGER! Test of the hydraulic system should be done very cautiously. There may be air trapped in the system which
can cause violent movements of the boom.
€
DANGER! Hydraulic leaks: Never use your fingers to locate a leakage in any part of the hydraulic system. Due to high
pressure, hydraulic oil may penetrate the skin.
Requirements for Tractor
The following requirements apply to both SPB and SPC types of the EAGLE boom.
Y-model Requirements
• One single acting outlet for raising/lowering of the spray boom.
• One double acting outlet for folding/unfolding the boom.
μ
ATTENTION! The hydraulic hoses are marked with arrows to indicate the direction of oil flow.
Other Information
The hydraulic system requires:
• an oil pressure of 190 to 210 bar. Minimum oil pressure is 180 bar to obtain correct operation. Maximum permissible
oil pressure is 210 bar.
• an oil capacity of approximately 35 litres.
• Return flow restriction of the connected tractor must be maximum 10 bar.
• For Load Sensing systems, an oil flow of approximately 5 l/min at 25 bar is supplied by the sprayer hydraulics. If a bigger
flow is required, a different orifice must be installed between the "open centre" hydraulic block and the load sensing
(LS) hydraulic line.
±
WARNING! Due to the variation in tractor hydraulic systems and capacities, care should be exercised when initially
operating the sprayer hydraulic cylinders. It is advisable to adjust the hydraulic flow control down to the minimum
rate before operating the system. If necessary, adjust/increase the flow control after the system is bled of any air.

ATTENTION! After having operated the boom and the system has been filled with oil, then check tractor's hydraulic
oil level and top up if necessary.
